siisch0: Timeout on slot 30

[Mailing Lists]

Morning All, 


I see there has been a few threads relating to something similar, specifically around port multiplier time outs using the SIIS module, with a patch even provided at one point - however this patch doesnt appear to be valid any more, 2 of the 3 chunks are already in the 8.2 release and from checking the cvs logs; when i try to apply, avoiding the roll back, 1 chunk does apply. I think the patch does make some difference, in that it doesnt make the disks stall for as long as frequently but the errors still appear in the logs. 

Currently running FreeBSD 8.2-RELEASE, with the zfs v28 patch. The main chassis has a Silicon Image 3124 in, with an estata port - connected to the esata port is another disk shelf with 5 disks in, all in one raidz pool. When i run a scrub on the external esata shelf, i see time outs in my logs:

siisch0 is the port multiplier , the slot number seems crazy to me (as i dont have 30 slots, theres only 5 in the external shelf) - although im not sure if this references something else. I dont believe this is a hardware problem, ive tried with replacement devices/controller cards, still see the above. 


Anyone else seeing this or have any thoughts? 

Thanks,
